Abstract

The invention discloses a tooth profile of a narrow-grooved milling cutter, belonging to a design technology of cutters and relating to an improvement on a narrow-grooved milling cutter. The tooth profile of the narrow-grooved milling cutter is characterized in that the narrow-grooved milling cutter has the cutterhead diameter d being 20-60mm, the tooth number being 8-12, the tooth groove angle theta being 50-60 DEG, the tooth groove depth h being 3-8mm, the rake angle gamma being 5-10 DEG, the primary relief angle beta being 12-18 DEG, the secondary relief angle alpha being 20-30 DEG and the margin width f being 0.8-1.2mm, and the side clearance angle delta arranged on two sides of the width of a cutterhead and from a knifepoint to the inner side of a cutter body is equal to 15'-1 DEG. By using the tool profile of the narrow-grooved milling cutter, smooth chip removal is realized, the cutter blade jumping phenomenon is avoided, the durability of the milling cutter is improved, and the surface roughness and the processing efficiency of a product are increased.

Description

technical field

[0001] The invention belongs to tool design technology and relates to the improvement of narrow slot milling tools. Background technique

[0002] There is a T-shaped narrow slot in a certain machine product, the slot width is 2.4mm, and the slot depth is 7mm. Due to the general milling cutter geometric parameters, the rake angle and back angle are large, and the number of teeth is large. Take a 60mm slot milling cutter as an example. The rake angle is 15°, the primary relief angle is 16°, the secondary relief angle is 35°, the number of teeth is 15, the cogging angle is 55°, and the cogging depth is 6mm. There is not enough chip space when processing products. When the milling cutter is re-cutting, the chip removal is not smooth, and the problem of tooth groove blockage often occurs, so that the tool cannot be cut normally, and the processing efficiency is low.
